At first sight these lancets
may seem like rather a mixed bunch, without much in common theologically.
There are some connections however, particularly between the first and
last lights which shouldn't present too much of a challenge to the DIY
exegete.

The second half of Jesus'
parable about Dives and Lazarus tells how the rich man, burning in Hell,
pleads with Abraham to send a warning to his surviving relatives of what
lies in store for them if they do not change their ways. Abraham however
rejects his plea, reminding him that; (Luke 16:29) "They have Moses
and the prophets; let them hear them". [...] and (16:31) "If
they hear not Moses and the prophets, neither will they believe, if one
rise again from the dead."

The episodes selected from
Moses' life for light A all have common exegetical interpretations, which
also appear in the earlier typological windows of the axial chapel (and
in similar windows at Sens, Bourges and elsewhere) - the burning bush
was a common antitype for the Virgin birth, the water brought forth in
the desert is the spiritual nourishment of the blood of the Crucifixion
and the brazen serpent is a common type for the Crucifixion itself. John
the Baptist is of course the last prophet to signal the coming of Him
who would rise from the dead. Thus the first two lights (A & B) present
the message of Moses and the life of the final prophet before Christ,
whilst light E contains a reminder of the importance of heeding the words
of Moses and the prophets. As for lights C & D on the other hand...
anybody's guess!
